Subsea electrification milestones in the North Sea (2015-2019)
Several North Sea operators deployed all-electric subsea systems on a pilot basis. Equinor (then Statoil) tested all-electric subsea trees and chokes on the Åsgard field, and TotalEnergies (then Total) deployed all-electric subsea actuation on the K5F project in the Dutch North Sea.
The pilots proved the core electric actuation technology worked in real subsea environments, logging thousands of hours of operation.
They built the operating-hours base that OneSubsea now cites (5 million+ hours) and set the stage for the larger JIP qualification programs in Brazil and Norway.
The Brazil JIP extends the same electrification principle proven in the North Sea pilots to deeper water (3,000 meters) and a more integrated architecture.
